Durable state

State is small permanent JSON memory shared by future runs of the same workflow ID and state location.

JavaScript

const current = await services.state.get("order-count");
const result = await services.state.increment(
  "order-count",
  1,
  { name: "increment-order-count" }
);

Method	Signature and behavior
`get<T>(key)`	`{ found: true, value, version, updatedAt }` or `{ found: false }`.
`has(key)`	`{ present, version? }`.
`set(key, value, { name, ifVersion? })`	Durable versioned write.
`delete(key, { name, ifVersion? })`	Durable conditional delete.
`increment(key, amount, { name, ifVersion? })`	Atomic durable counter.
`setIfAbsent(key, value, { name })`	Atomic one-winner durable initialization.

Every mutation requires a stable name. Retry with the same identity reattaches to the original committed result. Use ifVersion for compare-and-set. State does not expire, evict, enter context, or appear in normal run inspection. It is not transparently encrypted; protect the state file and backups and do not store secrets in state. Limits are 256 UTF-8 bytes per key, 256 KiB canonical JSON per value, 10,000 live keys, and 64 MiB of canonical values per workflow scope.
